SCADA FOR POWER SYSTEM AUTOMATION
ABSTRACT:
Automation of power distribution system has increasingly been adopted by power utilities worldwide in
recent years. As part of its efforts to provide a more reliable supply to the customer and to enhance
operational efficiency. The automation of the power system can be achieved by SCADA. It is a boon to
the automation concept of dynamic technology. SCADA refers to SUPERVISORY CONTROL
&DATA ACQUISITION .
This paper presents the approach adopted in implementing the SCADA system and the benefits
accrued through incorporating system. Electric power distribution system is an important part of electric
power system in delivery of electricity to consumers. Electric power utilities worldwide are increasingly
adopting the computer aided monitoring, control and management of electric power distribution system
to provide better service to electric consumers. Therefore research and development activities
worldwide are being carried out to automate the electric power distribution system utilizing recent
advancement in the area of information technology and data communication system. This paper reports
the present and past status of the research and development activities in the area of electric power
distribution automation both in developed as well as in developing countries. The information given in
this paper is useful to electric power distribution utilities and academicians involved in research and
development activities in the area of power distribution automation. Even public sectors like TNEB has
installed SCADA for monitor & control ninety-five substations in the CHENNAI metro for this, We are
trying to reproduce SCADA in a less paid form. This project explains the use of 8085 as RTU in power
system automation. Our ultimate aim is to reduce the cost but more user friendlier environment. This
may be a small step for us, we hope this may be a giant leap for the power sector. A computer based
SCADA system equipped with automated generation control function is proposed. To supervise and
control the generation and transmission system as well as to cater for their increasing sophistication in
system operation and coordination. In order to serve such a high number of RTU by a control centre and
to avoid any communication bottleneck at the master station, a distributed system approach is suggested.
Here two sets of dual computer system were installed at two geographically separated locations.
